Modern segmentation steps in
Modern segmentation overcomes the inherent inefficiencies of traditional techniques and, perhaps more importantly, results in stronger security for enterprise environments. Furthermore, it takes the concept of network segmentation down to a very granular, process-to-process level. It entails the creation of security policies around individual or logically grouped applications, regardless of where they reside in the hybrid data center. These policies dictate which applications can and cannot communicate with each other – true zero trust at the application level. Segmentation also makes it possible to apply policies in a dynamic fashion, so that as new workloads are spun up or down−or even moved, they are attributed to the correct policy automatically. This saves considerable resources by eliminating the need for manual moves, adds, changes, and deletes.
The key to implementing modern segmentation is to begin the process with a graphic visualization of all assets in the environment, whether bare metal, virtual machines or containers, and the dependencies between them. This deep visibility dramatically accelerates the process of identifying, grouping and creating security policies around the tiers of the applications.
By using modern segmentation enterprise administrators can provide security and enforcement at the application and process level, containing threats and alerting operators to their presence. In this way, modern segmentation is the most effective solution for reducing a company’s attack surface and risk profile. By enabling up to 30 times faster deployment than firewalls, and greater operational efficiency through simplified management, segmentation reduces both capital and ongoing operating expenditure compared to traditional techniques. Above all, a stronger security posture means reduced risks and liabilities without sacrificing any increased speed of innovation.
